A simple, efficient and environmentally benign protocol for the synthesis of methylenebisamides and carbinolamides in high yields from aromatic amides and formaldehyde in the presence of heterogeneous catalysts (Hβ and NaY zeolites) using water as a solvent is demonstrated. Moreover, the catalyst is recyclable and can be reused without significant loss in its catalytic activity.
在水为溶剂的非均相催化剂(Hβ和NaY沸石)存在下,从芳族酰胺和甲醛以高收率合成亚甲基双酰胺和甲醇酰胺的简单,有效和环境友好的方案得到了证明。此外,该催化剂是可回收的,并且可以在不显着损失其催化活性的情况下被重复使用。
